Frequently asked questions
Is my text sent to a server?
No. All conversions run locally in your browser. Nothing is uploaded or stored.
Does it keep my line breaks?
UPPERCASE, lowercase, Title and Sentence case preserve your spacing and line breaks. The code cases (camel, snake, kebab, Pascal) collapse text into a single token by design.
Can I undo a conversion?
Each button converts from the current text. Use your browser's Ctrl/Cmd+Z inside the box to undo, or re-paste your original.
